Reach preparation enhances visual performance and appearance.
We investigated the impact of the preparation of reach movements on visual perception by simultaneously quantifying both an objective measure of visual sensitivity and the subjective experience of apparent contrast. Using a two-by-two alternative forced choice task, observers compared the orientation (clockwise or counterclockwise) and the contrast (higher or lower) of a Standard Gabor and a Te...
متن کاملModeling Vehicle Occupant Head and Head Restraint Positions
In January 2001, NHTSA issued a Notice of Proposed Rulemaking (NPRM) concerning the regulation of automobile head restraints in Federal Motor Vehicle Safety Standard (FMVSS) 202. This report presents analyses of occupant posture and position data that were conducted in preparation for comments from UMTRI on the NPRM. The focus of this report is on the potential impact of head restraint geometry...
متن کاملWhiplash injury prevention with active head restraint.
BACKGROUND Previous epidemiological studies have observed that an initial head restraint backset greater than 10 cm is associated with a higher risk of neck injury and persistent symptoms. The objective of this study was to investigate the relation between the active head restraint position and peak neck motion using a new human model of the neck. METHODS The model consisted of an osteoligame...
متن کاملChronic restraint stress enhances radial arm maze performance in female rats.
Effects of chronic restraint stress (21 and 28 days) on physiological and behavioral parameters in female rats were examined. Total (bound and free) and free corticosterone (CORT) levels were measured at different time points during the stress period. Higher total CORT levels were observed in stressed rats during the stress period but returned to baseline at 15 days post-stress. Additionally, f...
متن کاملHead-slaved Tracking in a See-through Hmd: the Effects of a Secondary Visual Monitoring Task on Performance and Workload
Technological advances in helmet-mounted displays (HMDs) have permitted the design of “see-through” displays in which virtual imagery may be superimposed upon real visual environments. The utility of see-through displays in multitask environments remains uncertain, especially in environments that involve switching one’s attention between those tasks represented in the virtual display and those ...
